A power supply apparatus includes a power supply unit configured to wirelessly supply power to a power receiving device, a first communication unit configured to perform short-range wireless communication and include a first communication mode and a second communication mode, a second communication unit configured to perform wireless communication, a selection unit configured to select the first communication mode or the second communication mode as a communication mode of the first communication unit in accordance with whether the power supply apparatus is in a first mode, a second mode, or a third mode, and a control unit configured to control the communication performed by the first communication unit in accordance with the communication mode of the first communication unit selected by the selection unit.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A power supply apparatus comprising: a power supply unit; a first communication unit; a second communication unit; and a control unit configured to control the power supply apparatus to wirelessly supply power to a power receiving device the power supply unit, and wirelessly communicate with the power receiving device via the first communication unit; wherein in a case where the power supply apparatus wirelessly supplying power to the power receiving device via the power supply unit, the control unit determines, based on capability of the power receiving device, whether the first communication unit operates in a peer-to-peer initiator mode (P2P mode) or a reader/writer mode, and wherein, in a case where the power supply apparatus wirelessly communicates with the power receiving device via the first communication unit, the control unit determines, based on an authentication mode for wireless communication executed by the second communication unit, whether the first communication unit operates in the P2P mode or the reader/writer mode.
2. The power supply apparatus according to claim 1 , wherein, if the power supply apparatus power supply apparatus wirelessly supplies power to the power receiving device via the power supply unit, the control unit determines, based on capability of the power receiving device and an operation mode of the first communication unit, whether the first communication unit operates in the P2P mode or the reader/writer mode.
3. The power supply apparatus according to claim 1 , wherein, if the power supply apparatus wireless supplies power to the power receiving device, the control unit performs control in such a manner that after the first communication unit operates in either the P2P mode or the reader/writer mode, power is wirelessly supplied to the power receiving device via the power supply unit.
4. The power supply apparatus according to claim 1 , wherein, the first communication unit in an operation in either the P2P mode or the reader/writer mode is smaller than power wirelessly supplied to the power receiving device via the power supply unit.
5. The power supply apparatus according to claim 1 , wherein, power supplied to the power receiving device via the power supply unit is determined based on information received from the power receiving device as a result of the first communication unit having operated in either the P2P mode or the reader/writer mode.
6. The power supply apparatus according to claim 1 , further comprising: an antenna, wherein the antenna is shared between the power supply unit and the first communication unit.
7. The power supply apparatus according to claim 1 , wherein, if a settlement process is performed, the control unit causes the first communication unit to operate in the reader/writer mode.
8. The power supply apparatus according to claim 1 , wherein the first communication unit performs the short-range wireless communication on the basis of near field communication.
9. The power supply apparatus according to claim 1 , wherein the second communication unit performs the wireless communication using a communication method different from a communication method used by the first communication unit.
10. The power supply apparatus according to claim 1 , wherein the second communication unit performs the wireless communication using a wireless local area network.
11. The power supply apparatus according to claim 1 , wherein the second communication unit performs the wireless communication using Bluetooth.
12. A method for controlling a power supply apparatus including a power supply unit, a first communication unit, and a second communication unit, the method comprising: controlling the power supply apparatus for wirelessly supplying power to a power receiving device via the power supply unit and wirelessly communicating with the power receiving device via the first communication unit; wherein in a case where the power supply apparatus wirelessly supplying power to the power receiving device via the power supply unit, whether the first communication operates in a peer-to-peer initiator mode (P2P mode) or a reader/writer mode is determined based on capability of the power receiving device; if the power supply apparatus wirelessly communicates with the power receiving device via the first communication mode, whether the first communication unit operates in the P2P mode or the reader/writer mode is determined based on an authentication mode for wireless communication executed by the second communication unit.
13. A recording medium storing a program for causing a computer to execute a method for controlling a power supply apparatus including a power supply unit, a first communication unit, and a second communicating unit, the method comprising the steps of: controlling the power supply apparatus wirelessly supplying power to a power receiving device and wirelessly communicating with the power receiving device via the first communication unit; wherein, in a case where the power supply apparatus wirelessly supply power to the power receiving device, whether the first communication unit operates in a peer-to-peer initiator mode (P2P mode) or a reader/writer mode is determined based on capability of the power receiving device; if the power supply apparatus wirelessly communicates with the power receiving device via the first communication unit, whether the first communication operates in the P2P mode or the reader/writer mode is determined based on an authentication mode for wirelessly communication executed by the second communication unit wherein the second mode includes a mode for performing a communication performed by the second communication unit.
